Lull Privacy Policy
Effective September 15, 2026
Lull has no account and no analytics, and it does not track your sleep. Your sounds, mixes and settings stay on your phone. The only parts of the app that reach the internet are advertising and checking a subscription.
This policy explains what Lull (the “App”) does with information on iOS and Android. It is written to be read, so it says plainly what happens and where.
Polari Group LLC operates the App. If anything here is unclear, email us at support@polarigroup.com and we will answer it.
The Short Version
There is no account and no sign-in. Every sound is bundled with the App and plays without a connection. The App does not listen through your microphone, does not use your location, does not measure or score your sleep, and contains no analytics. What you play, when you play it and how you set it up stays on your phone. Advertising, which a subscription removes, and a check of whether you have a subscription are the only things that use the internet.
Information Stored on Your Device
The App stores the following on your device only:
- the sounds and levels you last played, your volume, and your saved mixes
- your timer and fade-out choices
- your preferences — auto-play at bedtime, keep playing when locked, bedside dim, download over cellular — and your bedtime reminder time
- the answers you pick during setup about what you want from the night and what keeps you up, which are used only to choose the first sound shown to you
- whether you have finished setup
This data never leaves your device through the App’s own code. We cannot see it, read it or restore it. Deleting the App removes all of it.
Widgets and the Lock Screen
To show what is playing, the App shares the current sound’s name, description, artwork, volume, and timer with its own widgets and with your phone’s lock-screen and media controls. On iPhone this is written to a storage area shared only between the App and its widgets. It stays on your device and is not sent to us.
Notifications
If you turn on the bedtime reminder, the App schedules a daily notification on your phone at the time you chose. It is created and delivered on the device; no server is involved. On Android the App also shows a media notification with playback controls while a sound is playing. You can turn notifications off at any time in your phone’s settings.
Advertising
The free version of the App shows advertising supplied by Google AdMob. AdMob may request ads from partner networks — Liftoff Monetize, Unity Ads and Meta Audience Network — to fill them. These providers may collect information from your device to select and measure ads, including an advertising identifier, device and app information, and approximate location inferred from an IP address. Their handling of that information is governed by their own privacy policies.
Where the law requires it, a consent form from Google is shown before any ad is requested, and a Privacy options entry in the App lets you change your choice later. On iPhone, the App asks through Apple’s App Tracking Transparency prompt whether it may use your advertising identifier for tracking. Declining is respected in full: the App works the same and shows non-personalized advertising instead.
Subscribers to Lull Premium are not shown advertising, and the App does not start the advertising SDK for them.
Subscriptions
Lull Premium is sold through the Apple App Store or Google Play, which process your payment. We never see your payment details. The App uses RevenueCat to confirm whether your subscription is active; RevenueCat receives an anonymous app identifier and the purchase information the store provides, and nothing that identifies you by name.
Analytics
The App contains no analytics. We do not measure sessions, screens, taps or retention, and we do not know which sounds you play, how long you listen or when you go to sleep.
Children
The App is not directed to children under 13, and we do not knowingly collect information from them.
Your Choices
You can decline notifications, decline tracking, change your advertising consent from Privacy options, and subscribe to remove advertising entirely. Deleting the App deletes everything it keeps on your device. Because we hold no account or listening data about you, there is nothing on our side to request or delete; questions about advertising data can also be directed to the providers named above.
Changes
If this policy changes in a way that matters, the effective date above changes with it and the new version is published here before the change reaches the App.
